DETACHABLE RESERVOIR FOR PENS.

SPECIFICATION forming part of Letters Patent No. 299,499, dated May 27, 1884.

Application filed October 25, 1883. (No model.)

To all whom it may concern:

Be it known that I, GEORGE WAsHINGroN WooLLEY, a citizen of the United States, residing at Washington, District of Columbia, have made Improvements on Reservoir Attachments for Pens; and I hereby declare that the following is a full and accurate description thereof, reference being made to the accompanying drawings, and to theletters and figures marked thereon.

I construct a shank to the reservoir,which, being applied to the pens concavity and insorted with it into the holder,will be held in it securely, and, being made of durable material, it lasts for many years, and is convenient and desirable for use in penmanship and drawing for many reasons, among which are the following: It fills as quickly with the pen as the pen does without it by dipping. plicable to the common pen-steel or gold does not affect the pens elasticity or fineness, and increases the pens capacity for writing from a single dip twenty to fifty times, by

writing a page or several pages of cap paper, according to the size of the reservoir and the number of its tongues or valves.

Myimprovements are described hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 represents a pen with its concavity exposed and the ink-holding reservoir placed in position. Fig. 2 is a bottom view of the reservoir having a single valve Fig. 3, a longitudinal section of the reservoir provided with a series of valves, and Fig. 4 a bottom view of the reservoir Without a valve.

In Fig. 1 the reservoir 0 is shown in the pen a ready to be inserted into the holder, its point being within about an eighth of an inch of the point of the pen,its shank b extendingto about the upper end of the pen. It will be seen that there is a perforation or air-duct, 0, in the upper end of the body of the reservoir, and also one, 6, near it in the shank. These are for the transmission of air from an d into the reservoir, which facilitates its filling n1 dipping and its shedding ink freely when in use.

In Fig. 2 the reservoir is of medium size, with a single. valve or tongue, d, extending from the air duct at 0 to within about an It is apeighth of an inch of the point of thereservoir. At about the same distance is a slight niche or excavation, extending to its point. This excavation is made by cutting back from the point of the reservoir 011 its under surface about an eighth of, an inch, as clearly shown at h, or What may answer thesame purpose, by leaving a little rotundity of the edge of the sides back of that point. The object of this cut-away portion is to prevent the reservoir for about an eighth of an inch back from the point from pressing against the pen, in order that the action of the reservoir and pen may not be impaired. This feature greatly facilitates the free flow of ink from the pen, as well as filling the pen and reservoir in dipping, prevents clogging, and at the same time prevents the attachment from impairing the proper function of the pens nib.

When the reservoir is furnished with a tongue or valve, it should be made of alloyed gold or other elastic material, so that its free end shall always spring against the pen, and not adhere to the bottom of the reservoir, nor touch its sides.

In Fig. 3 is shown the largest reservoir, containing four valves, the end of the longest-extending to about an eighth of an inch of the point of the reservoir, and the other three successively about an eighth of an inch shorter,

reservoir, as seen in the drawings. This large four-tongued or valved reservoir is for the largest gold or steel pens, that maybecarried in a case with a dip of ink in an air-tight holder during a day or night, and will Write a page or two of cap paper, if required,without redipping.

In Fig. 4 the reservoir is without a tongue or valve, but has the perforation in the reservoir and shank with a crevice between them, which may be useful in some cases by increasing the transmission of air.

What I claim is 1. An ink-ho1ding attachment for pens,consisting of a reservoir and a shank, each provided with an air-opening near the upper end of the bulb of the reservoir, substantially as set forth. I

2.
